Yes, it is. You dissolve your substance in the smallest amount possible of something suitable, hot - often ethanol. Then you cool it down and the substance should solidify. You filter to keep the solid and get rid of the impurities in the liquid. The trick is choosing the solvent wisely so that you get a good solubility when hot and not when cold.

∙ 9y agoOn normal basis you would not use crystallization as one of the methods for purifying substances. However to answer your question, crystallization alone can not purify anything. When a substance crystallizes it goes though evaporation, so when you crystallizes matter you are purifying it through the process of EVAPORATION. You can purify salts and other granular matter that would dissolve, though the process of crystallization and evaporation.

Water crystlization compound?
Water of crystallization is a complex compound with simple constituent elements.
How are a compound and a pure substance different?
Compounds and substances are practically synonyms; a compound or substance may be impure (contain impurities) or pure ( the impurities are only as traces or absent).
What is the addition of minor impurities to an element or compound called?
doping
What is water of crystallisation?
The water of crystallization is a type of water contained in the molecular structure of a compound.
How do you separate a chemical compound from its base?
Neutralized the base completely and then evaporation and crystallization may be be used.
What is the difference between a chemical compound and a pure chemical compound?
A difference of quality; the pure chemical compound is a refined compound, having a very low concentration of impurities.
How do you convert impure sample of salt into pure?
By using repeated cycles of fractional crystallization. On each cycle the impurities will concentrate in the brine, leaving purer crystals of salt.
What is the principle of zone refining?
principle behind zone refining is fractional crystallization; it is a process of separation of solute from its solution.
